High level summary​

We've implemented a feature for the next intra-era hard fork that enforces a property that is desired by the consensus componenet, which enforces uniqueness of VRF keys used by stake pools. Furthermore, we've progressed with PlutusV4 integration into Dijkstra era. Besides new features we've also tackled some tech debt and fixed a bug with JSON decoding of Alonzo Genesis file.
